OPERATING MECHANISM FOR PUMPS. v

Specification of Letters Patent.

Patented May 30, 1916.

To all whom it may concern:

Be it known that I, THOMAS B. YET'IER, a citizen of the United States, residing at Fountain Green, in the county of Hancock and State of Illinois, have invented certain new and useful Improvements in Operating Mechanism for Pumps; and I do declare the following to be a full,'clear, and exact description of the invention, such as will enable others skilled in the art to which it apuse the same.

My invention relates to improvements in pumps and more particularly to those adapted for use in comparatively deep wells.

The object of the invention is to provide a pump of this character which will be comaratively simple and inexpensive, which will be easy to operate, and which will cause a steady continuous flow of water. In carrying out this object, I provide certain novel features of construction and combination herein described and claimed and shown in the drawings wherein Figure 1 is a side elevation of a pump constructed in accordance with my invention, showing its application to use; Fig. 2 is a view similar to Fig. 1 but showing parts in section; Fig. 3 is a top plan view..

In these drawings, constituting a part of the present application, the numeral 1 designates a pipe line which leads from the lower end of a well W to a suitable point above the water level therein, at which point it is connected by a coupling 2 to the lower end of a casing 3, said coupling being provided with an upwardly opening check valve 4, whereby water is allowed to rise into the casing 3, but is prevented from flowing downwardly therefrom.

Threaded into the upper end of the casing 3, near one of its sides, is a main pump barrel or cylinder 5 whose upper end is connected by a coupling 6 to a pipe line 7 depending from the pump body 8 which is located above and rises from the usual platform P.

Lying parallel with the main is an auxiliary cylinder or barrel 9 whose upper end is closed by a cap 10 and is provided with a number of openings 11, directly below said cap, these openings allowing the entrance of air into and the passage of air from the cylinder 9 in a manner to be set forth.

Mounted for reciprocation in the main barrel 5, is a piston 12 which is equipped with an "upwardly opening check valve (not cylinder 5,

-revolubly mounted shown) and with a depending cage 14:- To

this cage 14: is securedthe upper end of one arm of a U-shaped connecting rod 15, the bend of said rod being located in the casing 9 while its other arm rises within the auxiliary cylinder 9 and is connected to a piston 16 which reciprocates therein. By this con; struction, it will be seen that reciprocation of the piston 12 will likewise reciprocate the piston 16. v I

Rising from the piston 12 and secured thereto by any appropriate means, is a piston rod 17 which passes slidably through a stufling box 18 on the upper end of the pump body 8, the upper end of said rod 17 being equipped with a toothed rack 19 with which a gear segment 20 meshes. is formed integrally with one end of a lever 21 which is fulcrumed between its ends at 22, the segment 20 constituting the resistance arm of the lever while the remaining portion thereof constitutes the power arm thereof. This power arm is provided with a longitudinal slot 23, through which an antifriction roller 24: passes, said roller being carried by and between the arms 25 of a forked operating lever 26, the ends of said arms 25 being 'fulcrumed at 27 upon a trans verse pin which is spaced laterally a suitable distance from the fulcrum 22. p

' By this construction and arrangement parts, wise oscillate the lever 21 to reciprocate the rack 19,'but the provision of said lever 26 allows the rack to be reciprocated with of pumps having gear and rack connections between their piston rods and handles.

Although the fulcrums 22 and 27 of the levers 21 and 26 might'well be mounted on any appropriate form of support, they are here shown as extending transversely between a pair of plates 28 which are formed integrally with the upper end of a post or standard 29 which rises from the pump body 8. It will be seen that these fulcrums are located near one end of the plates'28, while an anti-friction and guiding roller 30 is between the. other ends thereof, said roller bearing against the unmutilated edge of the rack 19 and serving to retain the same in mesh with the segment 20. r

In constructing the device as above. de-

This segment 20 r mental rightpump rod, a

check valve in the piston 12 scribed, it becomes necessary to arch the power arm of the lever 21 as seen at 21, this arch being located directly above the fulcrum pin 27 and being provided in order that said lever may move downwardly to the necessary extent without contacting with said pin. IV hen the handle is moved down to such an extent, however, as to allow the arch 21 and the pin 27 to contact, the clownward movement of said handle is limited, thereby preventing breakage of the interior parts of the pump which might be caused if such stop mechanism were not provided.

In operating the device, the handle is oscillated a plurality of times to fill the easing 3 with water, it being understood that the upward stroke of the two pistons 12 and 16 will draw such water into the easing, while the downward stroke thereof will cause the check valve 4 to close while the opens, the piston 16 now forcing the water downwardly out of the barrel 9 and upwardly into the barrel 5 and through said check valve. IV hen the pistons are again raised, the water above the piston 12 will of course be lifted and discharged from the spout of the pump, while more water will be drawn into the casing 3. The above mentioned operation takes place continuously as long as the handle is oscil- .lated, thereby discharging a continuous stream from the spout S. This is clearly advantageous over the ordinary form of pump which merely lifts the water when the single piston is being raised, but does not act upon said water when the piston is being lowered.

I have described the invention with considerable detail and have set forth certain specific formations for carrying out the ob jects of the invention, but it is to be understood that I do not wish to be limited to these details, otherwise than as set forth in the appended claims.

While the drawing shows a rack and seggear or quadrant connection between the pump rod and the lever, it will be understood that a link or any other form of connecting mechanism may be employed.

I claim: 7

1. In combination, a pump body, an upstandard rising from said body, a pair of spaced horizontal plates carried by said standard and extending rearwardly from the rod, the latter being received slidably between said plates, a hand lever having its front end forked and having the arms of the fork fulcrumed to the rear ends of the plates, a shorter lever confined throughout the greater part of its length between the fork arms and plates and having a sliding connection at its rear end with said fork arms, a fulcrum pin fiopieaoi this patent may be obtained for five cents each, by addressing the Washington, D. G."

passing through the plates and through the .shorter lever at a point spaced in advance of the fulcrum of the hand lever, and power transmitting means connecting the front end of said shorter lever with the pump rod.

2. In combination, an upright rack bar to be reciprocated for actuating a pump or the like, a pair of spaced parallel fixed plates extending rearwarclly in respect to said rack bar, the teeth of the latter being formed on its rear edge, a hand lever having a forked front end and having the arms of the fork disposed contiguous to the rear ends of the plates, a fulcrum pin passing through said rear end and through the fork arms, a gear segment meshing with the teeth of the rack bar and mounted for oscillation between the two plates in advance of the aforesaid fulcrum pin, a shorter lever confined throughout the greater part of its length between the fork arms and having its front end bowed upwardly above the aforesaid fulcrum pin and joined to the gear seg ment, the rear end of said shorter lever being formed with a longitudinal slot, and a pin passing through the fork arms and received slidably in said slot.

3. In combination, a pump body, an upright pump rod, anupright standard rising from said body, a pair of spaced parallel horizontal plates carried by the upper end of the standard and extending both forwardly and rearwardly from the pump rod, an upright rack bar carried on the upper end of said rod and received slidably between the aforesaid plates, said bar having its teeth disposed on its rear edge, a roller mounted between the front ends of the plates and bearing against the front edge of said bar, a hand lever having its front end forked and having the arms of the fork disposed contiguous to the rear ends of the aforesaid plates, a horizontal fulcrum pin passed through said rear ends of the plates and through the fork arms, a gear segment meshing with the teeth of the rack bar and disposed between the two plates in advance of the aforesaid fulcrum pin, a comparatively short lever confined throughout the greater part of its length between the fork arms and having its front end arched over the aforesaid fulcrum pin, the rear end of said comparatively short lever being formed with a longitudinal slot, and a pin passing through the fork arms and received slidably by said slot.
